JOSEPH O. DEOKERT, PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO WILLIAM MANNCOMPANY, A CORPORATION OF PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 756,159, dated March29, 1904.

Application filed December 26, 1903. Serial No. 186,619. (No model.)

It further consists of novel details of conl` struction, all as will behereinafter fully set forth, and particularly pointed out in the claims.Y

Figure 1 represents my device in plan view. Fig. 2 represents atransverse section through the line w w, Fig. 1. Figs. 3 and 4 representtransverse sections through points indicated by the lines y y,respectively, but show the device in its retracted or collapsedposition. Fig. 5 represents a partial longitudinal section through thelines e a, Fig. l.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, 1 l designate clamping-jaws having baseportions 2, preferably flat, sides 3end plates 4, and guide-bars 5.Attached to lugs 6 on the sides 3 are transverse supports consisting ofcoacting rods 7 and tubes 8, adapted to telescope into each other, asclearly shown in Fig. 2. On the base portions 2 are securedangularly-extending ribs 9. Bridge-plates 10, shown as of angularcrosssection at each en'd of the device, engagebetween the base portions2 and the guide-bars 5 and are held in p'osition by alongitudinallyextending rod 11, rotatably mounted in bearings 12 on eachof the plates 10. The rod 11 is squared at its free end 13 to engage akey or like device, by which it may be rotated. Secured on the rod l1are collars 14, abutting against the bearings 12. Integral with orsecured on the rod 11 isa screw 15 of quick pitch, on which is mounted atraveler, consisting of a -nut 16 and wings 17, in which are grooves 18,correspondingA in shape and angular relation to the ribs 9 and embracingthe Same. A back plate 19, having vertically-extending flanges 20 at itsends, is secured by screws 21 to the bridge-plates 10, and I have shownblocks 22 between said back plate and said bridge-plates.

The operation of the device will be readily understood from aninspection of the drawings. Where the device is used as a looseleafledger, to which it is particularly adapted,sheets of paper suitablynotched are slipped over the supports formed of the telescoping rods 7and ,in any desired number and are securely'grasped between the jaws byrotating the rod 11, so as to draw the jaws together. It is evident thatthis action takes place by the movement of the traveler on the rod, bywhich the ribs 9 move in the grooves 17, the parts being held againstlongitudinal movement and free to move laterally, the base portions 2and guide-bars 5 sliding on the bridgeplates 10.

It is evident that the bridge portions 10, which are within and. extendbetween the jaws 1, being held asunder by the rod 11 and bearing againstthe end pieces 4 of the jaws, act to prevent relative longitudinalmovement of the jaws, while guiding their transverse Amovement andholding them in the same plane.

The rods 7 and tubes 8, on which the leaves, pamphlets, `or the like areengaged, also assist in restraining and guiding the relative movement ofthe jaws. For this reason the device is practically complete, so far asits clamping and holding functionsvareconc'erned, without the back plate19. This merely serves to cover the opening of the back portions 2 whenthese are separated and may be made perfectly flat, as shown. Thisadapts it to be covered' with leather or the like from end to I end, sothat no metal is exposed.

It will be noted that the back of my device is practically flat and itrises only a very short distance above the desk or table on which it islaid. In this way the tendency of the back to roll when in use isprevented and a maximum proportion of the ledger-leaves is made usefulfor writing purposes.

It will be 4evident that various changes may be made by those skilled inthe art which will come within the scope of my invention, and

I do not, therefore, desire to be limited in every instance to the exactconstruction herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. A binder comprising a pair of clampingjaws held against longitudinalmovement, means for moving said jaws to and from each other, bridgeportions within and bearing upon said jaws and guides on said jawsadapted to sliding movement on said bridge portions.

2. A binder comprising a pair of clampingjaws held against longitudinalmovement, means for moving said jaws to and from each other, bridgeportions within and between said jaws, guides on said jaws adapted tosliding movement on said bridge portions and supports bearing upon saidjaws whether in their open or closed positions.

3. A binder comprising a pair of clampingjaws held against longitudinalmovement and having base portions, means for moving said jaws to andfrom each other, bridge portions within and extending between said jawsand bearing against said base portions and guides on said base portionsalso bearing against said bridge portions whereby said bridge portionsare adapted to retain said clamping-jaws in suitable relation to eachother during their movement.

4. A binder comprising a pair of clampingjaws held against longitudinalmovement and having flat base portions, means for moving said jawstransversely to and from each other, bridge portions within andextending between said jaws and bearing against said base portions andguides on said jaws also bearing against said bridge portions, wherebysaid bridge portions are adapted to retain said clamping-jaws in planerelation to each other during their transverse movement.

5. A binder comprising a pair of clampingjaws having base portions, alongitudinal rod, a traveler on said rod, said traveler and said baseportions being provided, the one with angular ribs and the other withangular grooves adapted to engage with said ribs, bridge portions inwhich said rod is rotatably mounted, said bridge portions being withinand extending between said clamping-jaws and guides on saidclamping-jaws adapted to sliding movement on said bridge portions and toprevent the relative longitudinal movement of said clamping-jaws whilepermitting their transverse movement.

6. A binder comprising a pair of clampingjaws having base portions,angularly-disposed ribs on said base portions, a longitudinal rod, atraveler on said rod having angular grooves adapted to engage with saidribs, bridge portions in which said rod is rotatably mounted, saidbridge portions being within and extending between said clamping-jawsand guides on said clamping-jaws adapted to sliding movement on saidbridge portions and to prevent the relative longitudinal movement ofsaid clamping-jaws while permitting their transverse movement.

7. A binder comprising a pair of clampingjaws, means for moving suchjaws transversely to and from each other, bridge portions within andextending between said jaws, guides on said jaws adapted to slidingmovement on said bridge portions whereby said bridge portions areadapted to retain said clampingjaws in plane relation to each otherduring their transverse movement and additional sliding means in saidjaws formaintaining such plane relation.

8. A binder comprising a pair of clampingjaws having iiat base portions,means for moving said jaws transversely to and from each other, bridgeportions within and extending between said jaws, guides on said jawsadapted to sliding movement on said bridge portions and a substantiallyfiat plate adapted to cover the space between said jaws.

9. A binder comprising a pair of clampingjaws, means for moving saidjaws transversely to and from each other, bridge portions Within andextending between said jaws, guides on said jaws adapted to slidingmovement on said bridge portions and a plate secured to said bridgeportions and covering the space between said jaws.

l0. A binder comprising a pair of clampingjaws, guides on said jaws,bridge portions within and extending between said jaws on which saidguides have sliding movement, a rod extending between said jaws androtatable therein, a screw on said rod, a traveler on said screw andcooperating devices on said traveler and said clamping-jaws whereby saidjaws may be transversely moved.
